Question

How is the kinetic energy of the particles that make up a substance different

after it changes state?
A. The kinetic energy is less after a substance changes from a liquid
to a gas.
OB. The kinetic energy is less after a substance changes from a gas to
a plasma
C. The kinetic energy is greater after a substance changes from a
liquid to a solid
D. The kinetic energy is greater after a substance changes from a
solid to a liquid.

Answer 1

D. The kinetic energy is greater after a substance changes from a solid to a liquid

Step-by-step explanation:

Answer 2

D. The kinetic energy is greater after a substance changes from a

solid to a liquid

Step-by-step explanation:

During a phase change from solid to liquid, the particles making up the mobile becomes more mobile and as a result there is an increase in kinetic energy of the system.

• Kinetic energy is the energy accrued due to the motion of a body.
• In a melting process where solids turn to liquid, there is an increase in kinetic energy.
• When randomness of a system increase, kinetic energy also increases.
• From liquid to gas and gas to plasma increases kinetic energy.
• In the other way round, the kinetic energy reduces.
